Shaft B5 is journaled in bearings 98 and 10 which are secured by the headed screws 1| and 12 respectively to plates 13 secured to the front leg member |012. Shaft `$5 is driven by a pulley 15 secured to one .end thereof over which runs one or more belts 16 also running over a pulley `11 secured to the driving shaft 18a of a reduction gearing unit 18. Unit 18 is mounted upon a bracket 19 supported on front leg member |012 and by a vertical member 19a extending to channel member` |0a. Unit 18 comprises a pulleyl 69 over `which runs a belt 6". 14 also running over the driving pulley 84 of a motor 89 Shaft 65 has secured thereto a cam 90 (see Figs. 9 and` 10). Cam 80 is arranged in alinement with and adapted to engage a roller 9| carried on a pin 92 extending between the arms of a lug 93a projecting upwardly from a lever arm 03 which has a hub journaled on a shaft 85 secured in and extending between projecting lugs on leg member I 0b. (See Figs. 4 and 9.) Shaft Ib5 has reduced threaded ends on which are secured nuts 89 and 81. One end of shaft 85. namely, the left-hand end as seen in Fig.. 9, extends through a bracket 90 secured by bolts 9| to the front leg member I0b. (See Fig. 16.) Bracket 90 is engaged by nut 81, Lever 93 is pivoted at one end by a suitable pivot 93 to a link 94 which extends upwardly.` Link 94 has socket members 94a at its ends threaded to `receive the threaded ends of rod 94h, lock nuts 94e being disposed on rod 94h and engaging the ends of members 94a. The length of link 94 can thus be adjusted. The upper end of link 94 is pivotally connected by a suitable pivot 96 to one end of a member 91 having a plate-like portion or lug threaded to receive a headed screw 9B (see Fig. 4). A bell crank lever 99 is pivotally connected intermediate the ends of 91 by a pivot |004. Bell crank lever 99 is pivotally connected at the end of its other arm by a pivot |0| to the bifurcated end of a link |02, which link is pivoted at its other end to a frame member |03. Member 91 is bored and threaded to receive a headed screw 98 equipped with a lock nut |05 engaging the side of member 91. Screw 98 has a reduced end extending into a compression spring |00 which is disposed between member 91 and the long arm of bell crank lever 99. A pin |01 is secured in the side of said long arm and'extends into the upper end of spring |06. A yoke |00 is pivoted to said long arm by a pin |09 and extends around one end of the lower portion of member 91 to limit its movement relative to bell crank lever 99. The frame member |03 extends upwardli7 from the channels Illa and is secured to said channel in any suitable manner, as by the brack ets |031) (see Fig. 2). Frame |03 is also supported at its front end by a bracket |030 secured to the bearing portions ID3-a and to channel Ida by headed screws |03cl. Said head has a front portioncomprising spaced bearings |0311 in which. is journaled a spindle ||0. A bushing III is secured in the top bearing |03a, the same havingr a flange overlying said bearing and extending some distance above said flange. The upper end of spindle ||0 is reduced and journaled in`bushing III. Spindle I|0 has a collar ||0a thereon some `distance above lower bearing |03a, as shown in Fig. 4, and the portion of spindle Ill just above said collar is engaged by the forked end of a lever arm I2, which lever arm is pivoted to the intermediate` portion of bell crank lever 99 by a pivot I I3. Lever I2 is pivoted intermediate its ends on a stud or shaft ||4 extending between the sides of frame member |03. The lower end of spindle H0 comprises a socket in which is secured a member I I6 having spinning or riveting jaws I Ilia at its lower end, as shown in Figs. 14 and l5; A pulley I I1 is journaled on the upper end of bushing I Il and secured to spindle I I0 by the keys II8. A steel washer ||9 is disposed in. the upper end of pulley 'I I1 and is engaged by the lower end of a coiled compression spring |20 the upper end of which is engaged by a collar or washer |2| secured on the upper threaded end of spindle ||0 and engaged by a nut |22 threaded 7. on said upper end. Pulley I I1 is provided with a peripheral groove of V or trapezoidal shape in which runs a belt which also runs over a pulley |26 having a peripheral groove similar to that of pulley |I1 and which is secured to the armature shaft I21a of a motor |21 secured to the side of frame |03. It will be seen that spring |20 urges spindle III) upwardly and that said spindle can be moved downwardly by action of lever ||2 which Will be in turn moved by bell crank lever 09 and member 91. Member 91 will be moved downwardly by lever 83 which in turn will be actuated from cam 80. In one cycle of the machine therefore the riveting head or jaws I I6a is moved downwardly to rivet the portion R! over the laminations of the plunger P, as shown in Fig. 15. This riveting is done with a rotating motion of members |I8a so that portion Ri is spun over the top washer P3.

A cam is secured to shaft 65 in any suitable manner as by the set screw ISI. A collar |32 is secured to shaft 65 by a set screw |33 and engages one end of cam |30. Cam |30 has its periphery in engagement with a roller |35 (see Figs. 9 and 11). Roller |35 is journaled on a short shaft |38 carried between the sides of a lever |31 and held in place by a cotterpin |38. Lever |31 has an opening therein, as shown in Fig. 16, in which roller |35 is disposed. Lever |31 has a yhub at one end journaled on a shaft or stud |40 extending through bracket 80 and having a reduced end on which is threaded a nut |4I. Lever |31 has a hub at its free end having a vertical bore therein and in which is threaded a headed screw |42, said screw being provided with a lock nut |43 which engages the hub on lever |31. The screw |42 is disposed in vertical and axial alinement with the screw 3| on one of the holders 28 when in a certain position on the chains II and I2, which position is indicated at I45a in Fig. 16. In one cycle of the machine therefore lever |31 will be actuated by cam |30 and its free end will move upwardly and engage the screw 3| to raise the sleeve 28 and the collet 33.

A cam |46 is secured to shaft 65 in any suitable rnanner, as by a set screw |41, said cam engaging at one end another cam |48 secured to shaft |55 by a set screw |49. Cam |48 in turn engages cam |30. Cam |46 at its other end engages a ball bearing |50 on shaft 65 disposed in a bore in bracket 80'. Cam |48 has a periphery engaging a roller journaled on a stud secured in spaced lugs I 56a of a lever |56. Lever |58 has a hub at its larger end journaled on shaft 85. The other end of lever |56 has a hub pivotally connected by pivot |58 to a link |60. Link |60 is pivotally connected at its other end by a pivot IBI to a lever |62. Link |60 comprises end socket members I'60a in which the ends of an intermediate rod are threaded, said rod being provided with lock nuts I60c engaging the ends of members I60a respectively. Lever |62 is pivoted intermediate its ends on a stud |63 secured in the lower end of a bracket |64 secured by suitable screws |65 to channel Illa. The other end of lever |62 is pivotally connected by a pivot |66 to link |81, which link is pivotally connected at its other end by a pivot |68 to a portion |1064 projecting from a slide |10 which is slidable in a guide member |1| secured by spaced screws |12 to the side of channel I0 and to the bracket 80. Slide |10 is of rectangular form in cross section and is held in place by retaining strips |13 through which screws |12 also pass. Slide |10 has concircumference of the plunger P.

8 nected thereto at its upper end by spaced'headed screws |14 a bracket |15. Bracket |15 underlies the plunger P and is engaged by portion P2 thereof, said bracket having an aperture |15a `therethrough in axial alinement with collet 33.

In one cycle of the machine therefore, which cycle follows the cycle in which the holder is elevated, cam |48 will actuate lever |56 which in turn through link |60 Will actuate lever |82 to elevate slide |10 and thus by bracket |15 elevating the plunger P and the plunger rod R, as shown in Figs. 4, 5 and '1.

Cam |46 engages a cam roller |80 (see Figs. 5, 9 and 13), which roller is mounted on a shaft or stud |8| mounted in spaced lugs extending upwardly intermediate the ends of a lever |82. Lever |82 has a hub at its larger end journaled on shaft 35 and has a hub at its other end pivotally connected by a pivot |83 to a link |84. The other end of link |84 is pivotally connected by pivot |85 to the short arm of a bell crank lever |86. Link |84 comprises end socket members |8417J into which the ends of the rod |835 are threaded, said rod having lock nuts |840 engaging the ends of members |84a. Link |84 can thus be adjusted in length. Bell crank lever |86 is pivoted on a stud |81 secured in a bracket mounted on the upper end of one of the brackets |035 and fastened by screws |88. The upper and long arm of bell crank lever |88 is pivotally connected by a pivot |90 to one end of a link ISI, which link is pivotally connected at its other end by a pivot |92 to a slide |33. Link ISI comprises spaced portions disposed at either side of the hub at the upper end of bell cra-nk lever |36 and the hub I93a secured to one end of slide |93 (see Figs. l, 4,. 5 and 8). Slide |93 reciprocates in a guide |04 secured by screws |05 to a bracket |86 Which is in turn secured to one side of housing |03. Spaced supporting pla-tes |31 extend horizontally from the end of guide |04, as shown in Figs, 1 and 8. The end of slide |93 opposite the hub |83a is of semi-cylindrical form and in the position shown in Fig. 8 is concentric with the When the plunger P and the rod R have been elevated as previously described, the plunger is brought into horizontal alinement with slide |93 and when cam |48 actuates lever |82 said slide is reciprocated through link |84 and bell crank lever |86, the same being moved to the right, as shown in Fig. 5, and to the left, as shown in Fig. 8. The plunger and its rod is moved horizontally and laterally and the plunger moves to a position on the plates |91 and rests thereon, as shown in Figs. 5 and y8. The completed and assembled plungers and rods can be taken from plates |91 by the operator.

The operation which has been briefly outlined above is as follows: The plunger rod R with the plunger loosely assembled thereon, as shown in Figs. 14 and 15, is placed in the holders 20 by the operator at the rear end of the machine. The chains I I and I2 are intermittently moved by the Geneva wheel 42 and the arm 52. Motor 'I8 will be operated and shaft 65 will be driven. Shaft 45 will be driven throughbeveled gears 5I and 80 and arm 52 will be rotated at constant and uniform speed in the direction indicated by the arrow in Fig. 16. In each revolution the roller 58 at one end of arm 52 will enter one of the slots or recesses 42a and will turn the wheel 42 through sixty degrees. The roller leaves the slot after wheel 42 has been turned to such an extent. One of the rods and plungers has now been brought `9` to the position |45` shown in Fig.` 16. At this time While the chains and |2 are at rest, cam

8|!` operates and the spindle ||0 is depressed through action of lever 83, link 04 and members 91, 09 and ||2. The spinning head or jaws ||6a are now brought down against portion Rl of .l the rod R and said portion is riveted` over the top washer P3 n and the parts of the plunger are pressed into very firm engagement. Head or jaws ||Sa are rotating andthe portion Rl is riveted with a spinning `action.` It will be seen that the pressure on spindle is produced with a yielding action due to the spring |05 disposed between members 91 and 09. The tension on this spring can be regulated by screw |84. The yoke |08 limits the movement of the lower portion of member 91 away from member 99. When the low partlof cam v8|] engages roller 8|, spindle H0 isr again elevatedby spring |20. The cycle of action of cam 80 is indicated in Fig. 10. `Arm 52 now engages another one of the recesses 42a and the conveyor carried by chains and |2 is moved another step and the riveted rod and plunger are now moved to position |45a, as shown in Fig. 16. It will be understood that as chains and |2 are progressed, the members 28 are carried along and supported by the rollers 25a. With the rod Rand plunger P in position |45a` and in the condition shown in Fig. 15, cam |30 now engages roller |35 and lever |31 is swung upwardly bringing the head of screw |42 into engagement with the head of screw 3| and this elevates portion 2819 of the holder so that the collet 33 is pushed upwardly. From Fig. 14 it will be seen that por@ tion 28h can move upwardly in the space shown in casing 28a. This upward movement of the collet loosens the same so that the rod R is not now gripped in said collet. Cam |30 could be called a knockout cam and its cycle of movement is indicated in Fig. 11. Wheel 42 is now moved through another sixty degrees and the rod and plunger operated upon are brought to the posi-` tion |451), as seen in Fig. 16. At this time and while the conveyor is stationary, cam |48 engages its roller |55 so that lever |56 is depressed and the end of lever |62 connected to the slide |10 is elevated by link |60. Slide is now elevated and the bracket or plate |15 is elevated carrying with it the plunger P and the rod R. The plunger is elevated to be in alinement with slide |93. While the plunger is in alinement with slide |93, cam |46 acts on its roller |30 and slide |Q3 is moved through link |84 and bell crank lever |8li so that slide |93 engages the plunger and moves the same onto the plates |91 so that it is supported on said plates with the rod R depending between said plates, as shown in Fig. 5. Slide |10 is now lowered and slide |03 again moved to the left, as shown in Fig. 5. The cycles of cams |46 and. |48 are indicated in Figs. 13 and 12- respectively. The rod R with the plunger P riveted securely thereto can now be taken oi the plates |91 by the operator` or said plungers and rods can be pushed off of said plates and received in any` The action is continued with the the operator has to do is place the assembled rod` and plunger in the holders 28. The machine acts automatically to progress the rods and plungers,`

secure the same together and deliver them. The machine has been amply demonstrated in actual practice and found to be very successful and eflicient. The same is being used to produce assembled rods and plungers which are used in devices marketed commercially.
